Description
The utility model belongs to a kind of surveying instrument, especially for the torque gauge of measuring cereal starch thin pulp viscosity.
Need to measure relation between cereal starch thin pulp viscosity number and the temperature in the food industry and determine the index of quality with more different starch.Being specifically designed to the torque gauge of measuring cereal starch thin pulp viscosity at present rotates the measurement alms bowl by the motor driven gear deceleration, a metal bar probe is counted sensor with direct insertion temperature, the probe lower end puts in measures the sensing unit that in the alms bowl starch thin pulp resistance is delivered to the measurement tube on top, sensing unit axle head plush copper is relative with the measure case shrinkage pool, shrinkage pool is pressed in left-right rotation on the sensing unit axle head plush copper, the recording pointer continuous recording gelatinization family curve of pen recorder.But probe constantly vibration becomes flexible sensing unit axle head plush copper and measure case shrinkage pool, the frictional influence that exists between the two measurement accuracy.
The purpose of this utility model is that a kind of friction loss of design is little, the torque gauge that precision is high.
The technical solution of the utility model comprises motor 17, gear pair 15, crank and rocker mechanism 14, support 13, beam type force transducer 7, temperature sensor 2, temperature and torsiograph 10.Crank and rocker mechanism 14 is fixedly connected with rotor 9 and makes rotor 9 swings, rotor 9 is installed in the casing 6 by rolling bearing, have groove on the rotor 9 beam type force transducer 7 is installed, force transducer 7 is connected to experience resistance with stirring rod 1 by link block 4, stirring rod 1 is made by the stainless-steel tube of 2 mm outer diameter, and temperature sensor 2 is housed in its hole.When rotor 9 swing, 1 pair of tested starch thin pulp of stirring rod applies external force, and the reacting force of starch thin pulp is measured by force transducer 7, and known again eccentricity then can be learnt the size of moment of torsion.Utilize the data of power and 10 pairs of collections of temperature measuring set to carry out record.And, on 17 on the motor gear pair 15 is housed, client link on the gear wheel on the gear pair 15 and the axle 12, axle 12 passes rotor 9, and its lower end connects stirring vane 16, and driven vane 16 is rotated continuously and is kept thin pulp even.And beam type force transducer 7 tow sides respectively are equipped with two and are screwed resistance strain gages 8 on pressing plate realizing temperature compensation and to increase output, sensor 7 tops by two finger settings on rotor 9 grooves.
The utility model does not have fricative influence, and motion has steadily reduced motor and rotated the vibration that force transducer is produced, and has improved the precision of measuring.
